I would ride it until it goes back out of true just to see how long it takes if the original problem was the wheel being out of true. I have had a couple of wheels that got bent so bad they were rubbing on the frame, either due to broken spokes in a crash or getting hit by a car. I trued them up and worked on spoke tension to try and even it out and they are still going strong many thousands of miles later. It really depends on exactly how you tweaked the wheel and how good the person who fixed it was. Note for my wheels though, the integrity of the rim wasn't damaged at all, the wheel was just out of true.
